The shooting left the man, identified as Mark Wayne Bill, 56, with "life-threatening injuries," according to Elizabeth Watts, Clearwater public safety spokeswoman, and he was in surgery at Bayfront Medical Center late Sunday.

Watts gave the following account of the incident, which happened at 7:13 p.m.:

A relative of the man contacted Clearwater police and expressed concern about a conversation he had with the man. The relative asked officers to check at the man's home in the 2200 block of Glenmoor Road.

When officers Kris Wise and Michael Beaver arrived, they found the man armed with an AR-15 semiautomatic rifle. He fired at least one shot at the officers, but they returned fire and hit him.

The man's 15-year-old son was at home at the time of the shooting, Watts said. He was not injured.

Wise and Beaver will be placed on administrative leave during the investigation, which is standard policy in officer-involved shootings.
